Of them, Diaspananthus Miq., Breea Less. and Stenactis Casso are included in Ainsliaea DC., Cirsium L. and Erigeron L., respectively, after Bremer(1994) in this index. The auther names for the tribes Inuleae, Plucheeae, Gnaphalieae, Helenieae and Eupatorieae and the genera Circium, Coreopsis, Galinsoga and Synedrella also follow Bremer (1994). This index contains two introduced genera, Centaurea and Zinnia, 18 species (two native and 16 naturalized) and one inter-specific hybrid in addition to those enumerated in Iwatsuki et al. 1995. The tribal classification and circumscription, and the presentation order of the tribe follow Bremer (1994). The number of genera and species examiried is given in Table 1~ Genera and species in each tribe are arranged in alphabetical order. The main table shows the year of publication of tribes and genera, the number of genera examined and the number of Japanese genera within each tribe, the number of species examined and the number of Japanese species within each genus, basic chromosome number for each tribe and genus, correct name of taxa, chromosome number, locality (Prefecture) of the specimen examined and references. The number of indi­ viduals examined is given in parenthesis after chromosome number. When the locality has not given in the original reference, its column is vacant. This index does not include chromosome counts for artificial hybrids. Chromosome number cited as nand 2n represent the gametic chromosome number recorded in meiosis and the somatic chromosome number in mitosis, re­ spectively. Ploidy level was estimated based on the abnormalities and ·size of pollen grains on herbarium specimens. Some botanical names used in the original reports have been changed and then all follow Iwatsuki et al. (1995). For dubious chromosome counts, question mark is given in parenthesis. Chromosome number survey on Japanese Asteraceae started in 1911 by Ishikawa and Tahara. Until the end of 1996 chromosome number of 379 species (84.8%) of 85 genera (90.4%) were determined by 356 references. Particularly three major schools, Tahara and his coworkers at Tohoku University, Ono and his coworkers at Tokyo Metropolitan University, and Shimotomai, Tanaka and their coworkers at Hiroshima University, have made a great 2 Proc. Jap. Soc. PI. Tax. Vol. 12(2) contribution on this progress. Chromosome number varies from n=4 (2n=8) in Crepis gymnopus and C. hokkaidoensis to n=60 (2n=120) in Parasenecio auriculata. Out of 379 Japanese Asteraceae species whose chromosome numbers are known, 77 species (20.4%) are polyploid and additional 37 species (9.8%) include polyploid as well as diploid within species. The highest ploidy level is a decaploid found in Dendranthema crassum, D. pacificum and D. yezoense (2n=10, x=90). Aneuploidy has been found in 20 species of 7 genera: i. e., Artemisia, Aster, Circium, Crepidiastrum, Dendranthema, Eupatorium and Parasenecio. Dysploidy has been found in Artemisia (x=8 & 9), Coreopsis (x=12 & 13), Ixeris (x=7 & 8), Lapsana (x=8 & 22), Parasenecio (x=26, 29 & 30) and Pertya (x=13 & 14). Both the frequencies of aneuploidy and dysploidy, however, are very low in the Japanese Asteraceae. B chromosomes have been found in 18 species under 9 genera: i. e., Anapha/is, Artemisia, Aster, Carpesium, Dendranthema, Gnaphalium, Petasites, Sausurrea and Taraxacum. Serious disagreements between reports have been revealed in Adenocaulon himalaica (2n=46 & 48), Carpesium abrotanoides (2n=36 & 40), Pertya (2n=24, 26 & 28), Carduus crisp us (2n=38 & 40), Ligularia angusta (2n=58 & 60), Ligularia hodgsonii (2n=58 & .60), Ligularia stenocephala (2n=58 &60), Miricacalia makineana (2n=52& 54), Petasites japonicum (2n=58, 60 & 87), Senecio flammeus (2n=46 & 48) and Senecio nikoensis (2n=10, 40 & 48). Further examination is needed for these species. These are not counted as aneuploidy or dysploidy in this index. Agamosperrny have been found in the genera Eupatorium, /xeris, Erigeron and Taraxacum. Systematic position of the genus Centipeda (x=lO) in the tribe Anthemideae (x=9) may not be correct from the stand point of basic chromosome number. Table 1.

The goal of the present study was to conduct a mor- phological and molecular phylogenetic analysis of the Cercospora spp. occurring on various plants growing in Northern Thailand, an area with a tropical savannah climate, and a rich diversity of vascular plants. Sixty Cercospora isolates were collected from 29 host species (representing 16 plant families). Partial nucleotide sequence data for two gene loci (ITS and cmdA), were generated for all isolates. Results from this study indicate that members of the genus Cercospora vary regarding host specificity, with some taxa having wide host ranges, and others being host-specific. Based on cultural, morphological and phylogenetic data, four new species of Cercospora could be identified: C.

  • It Is Noteworthy That the Hybrid Between Paraixeris Denticulata
    158 Cytologia 14 Intergeneric Hybridization in Cichorieae, VII. Cytology of F4 individuals of Paraixeris denticulata•~Crepidiastrum platyphyllum1 By Humihiko Ono Biological Laboratory, Matuyama-kotogakko Received April 21, 1946 Introduction It is noteworthy that the hybrid between Paraixeris denticulata NAKAI and Crepidiastrum platyphyllum KITAMURA is actually found in nature, which taxonomists describe as a new species or a member of a new genus. The present author has undertaken to investigate the origin and the nature of this plant since 1933. He crossed these two different plants and obtained a hybrid quite similar to the plant found in nature. Further the cytological behavior of the hybrid has been studied. The F, of the hybrid which had a low fertility, yielded some achenes when open-polli nated between the F1 individuals. The fertility became higher in each generation than the last. The cytological features of these offsprings up to F3 have been reported in the preceding papers of this series (ONO and SATO 1935, ONO 1937, 1938, 1941). In the fall of 1933, a rather large number of F4 individuals were obtained. Out of these individuals about one hundred were selected for investigation of their external morphology, somatic chromosomes, meiotic behaviors and fertilities. These investiga tions were expected to reveal the hereditary and evolutional significance of this hybrid, and further to elucidate to some extent the nature and the consequences of the structual changes in chromosomes. Another aim of the present study was to investigate whether it might be possible by crossing any two species to produce a fully constant and viable new type, which might prove of great significance in the problem of evolution.
